Three individuals connected to a recent attack that left nine Americans dead last month were detained by Mexican authorities Sunday, CBS News has confirmed. According to the report, the operation was a coordinated effort between Prosecutor General, the National Guard and the National Center for Intelligence.

The attack left three women and six children dead as they attempted to drive north in their vehicle. They were ambushed by deadly cartels as they passed through the State of Sonora.

In a recent turn of events, President Donald Trump says he is ready to designate the cartels “Foreign Terrorist Organizations.” In an interview with Bill O’Reilly last week, the President said, “they will be designated … I have been working on that for the last 90 days.”

“You know, designation is not that easy, you have to go through a process, and we are well into that process,” said Trump.

Sara A. Carter produced Not In Vein last year. The film highlights the devastating opioid crisis our country faces and the cartels’ role in manufacturing and trafficking that deadly poison into our country. Click here to watch Not In Vein.
